Which- Figure l represents a side elevation of a reclining-chairembodying my inventiomand Fig. 2 represeutsa back Viewot' the same.

Like letters of reference indicate like parts.

The object of my invention is to so con-` struct a chair as to admit ofbeing adjusted to suit the convenienceof the occupant, either in asitting or reclining position; and to that end myinvention consists inthe'combinationwith the back, hinged to the bottom or arms ofthe chair,of an adjusting-spring and tightening- Y bolt, whereby the back is heldfirmly in position, and at any desired incline, as is hereinafter morefully described.

In the drawing, Arepresents the frame-work constituting the base orbottom of the chair, A

which may be made in the form shown, or in any other form' that willsupport the cushion B. G is the back, which may be made in any suitableform that will admit of being hinged to the base or bottom in suchamanner as to allow the back to be inclined backward to any desiredposition. D is a curved metal spring, which is attached at one end tothe frame of the back above the hinges, and at theother end to the frameof the base or bottom below the hinges, as shown in Fig. 1. Eis anadjusting-bolt, which is so arranged as to pass through one of the sidenumbers of the back and base, as shown by dotted lines in Fig. 2. Theadjustment of the bolt is such that, when properly tightened, it holdsthe' back at anydesired inclination, at which it may be adjusted; andthearrangement of spring D is such as to yield and allow the back to beadjusted to the desired inclination, when force is applied to the upperpart of the back, and to force the back forward to itsnormal positionwhen the bolt is loosened.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

' The` combination, with the back C hinged to the base orv bottom A, ofthe spring D and bolt E, substantiallyas and for the purposel specified.y v JAMES W. MGDONOUGH. Witnesses:
